Real Estate Agent vs. Buyer's Agent: What's the Actual Difference

28 August 2026

"Real estate agent" and "buyer's agent" get used almost interchangeably by buyers, but they answer to different people, and in Spain that difference matters more than it does in markets you might be used to. Here's who actually works for whom, and why it's worth knowing before you start viewing properties in Mallorca.

Who's actually paying them

Spain doesn't have the system you might expect

In markets with a real MLS (Multiple Listing Service) and standard cooperating commissions, a buyer typically works with their own agent at effectively no direct cost: the seller's commission gets split between both sides automatically. Spain doesn't work that way. There's no true MLS here (we've written about that separately; Real Estate Websites covers how the portals actually function), and the default relationship is simple: the agent showing you a property almost always works for, and answers to, whoever's selling it.

It gets murkier still with dual agency, which is common enough in Mallorca to be worth naming directly: the same agent representing the seller can also be the one who "helps" you as a buyer, sometimes for a property they hold the listing on themselves. That agent is being paid by the seller to get the seller the best price, while simultaneously advising you on what to offer, two duties that pull in different directions, held by one person. It's not illegal, and for most straightforward purchases it's not a problem in practice either: plenty of sales complete perfectly well this way, and a seller's agent with broad market reach is often exactly who can move fastest and show you the most relevant stock. It's simply worth knowing whose interest that agent is ultimately answering to, so you can weigh their advice on price and condition accordingly.

What a buyer's agent actually does differently

A dedicated buyer's agent (sometimes called a property buying agent or agente comprador) works on your behalf specifically: usually for a set fee, often billed monthly for as long as the search takes, rather than a single commission at the end. That fee doesn't necessarily mean no commission changes hands, though: many buyer's agents also receive a completion commission once a sale goes through, paid by the seller, shared with the selling agency, or some combination, worth asking directly, since the answer varies agent to agent. In practice, working with a dedicated buyer's agent can mean access to off-market stock, more room to negotiate on price rather than a soft push toward the asking figure, and someone whose job includes catching problems with a property (planning status, licence issues, boundary disputes) before you're contractually committed rather than after, though that depends on the individual agent's own network and experience, the same as it does for any agency.

Neither model is simply "better": it depends on what you actually need. A buyer's agent isn't automatically a bigger or better pool of stock than a well-connected local agency; some have genuinely deep off-market access, others work from a narrower book than the agencies covering the general market. For a straightforward, lower-value purchase where you're comfortable doing your own due diligence, a regular estate agent with broad reach may serve you perfectly well. For a complex or high-value purchase, a purchase from abroad without being able to view repeatedly in person, or simply wanting someone whose only job is your side of the negotiation, a dedicated buyer's agent is a genuinely different service worth paying for: the right answer is about fit, not one model outranking the other.

Registering with an agency: the viewing document, and why exclusivity matters

When you first view a property through an agency, you're normally asked to sign a viewing document (often called a hoja de visita or nota de encargo). It looks like paperwork, but it's doing real work: it's the agency's record that they introduced you, specifically, to that property, at your request. If a sale later goes through, that document is what lets the agency claim their commission from the seller for introducing the buyer and seeing the transaction through.

The complication shows up when a buyer registers with several agencies at once, which is easy to do without realising it: Mallorca's property portals aggregate the same listings from many different agencies (see our Pay & Display Coverage breakdown for how widely one property can be duplicated across sites), so it's entirely possible to view the identical property twice, through two different agencies, each of whom now has their own signed record of having introduced you to it. If a sale later completes, both agencies can genuinely believe they're the one entitled to the commission, and sometimes both actually have a document that supports the claim.

This isn't a rare edge case; it's a known, recurring problem in the Mallorca market specifically because of how fragmented listing distribution is here. When it happens, the dispute is between the agencies, but the buyer and seller are the ones who end up caught in it: sales have genuinely fallen through over exactly this, either because the seller doesn't want to get pulled into a commission dispute they didn't cause, or because the buyer isn't willing to go through the process of the two agencies fighting it out (or, in the worst case, paying commission to more than one party for a single transaction).

The practical way to avoid it is to be deliberate about who you register with, rather than letting it happen by default. Working with one, or at most a small handful, of agencies you've chosen on purpose, rather than registering with every agency that replies to an enquiry, makes it far less likely two of them end up with an overlapping claim on the same property. Some buyers go a step further and sign a genuine exclusivity agreement with a single agency or buyer's agent, which is worth doing properly if you do:

• Put a finite time limit on it (three, six, nine or twelve months is typical) rather than leaving it open-ended. An agency confident in earning your business shouldn't need an indefinite claim on you to justify the effort.
• Confirm in writing how you can exit early if you find a property yourself, or through another agency, outside the scope of what they've actually shown you: a genuine exclusivity agreement should cover what they introduce you to, not lock you out of buying anything at all through anyone else.
• Ask for and actually read whatever you're asked to sign before you sign it, not after: a viewing document and an exclusivity agreement are different things doing different jobs, and it's worth knowing which one is in front of you and what it commits you to.

What to actually ask before you start

Before you view a property with any agent, it's a reasonable and normal question to ask directly: who do you represent, and who's paying you? If the answer is "the seller" (or the agent hesitates, or the property is their own listing), you're working with a seller's agent, however helpful they are to you personally, treat their advice on price and condition accordingly. If you want someone whose only job is your outcome, that's what a buyer's agent is for, and it's worth deciding which one you actually want before you're three viewings into a relationship that was never structured to be on your side.

If you already know what you're looking for, our Connect With a Partner Agent form asks exactly this question up front, so you're matched with the right type from the start rather than finding out which one you got partway through a negotiation.
